If the Virago uses its ability on a card with a trait specific enhancement, does that card loose it's enhancement?

For example, I am have The Virago and a couple fighters out. My oponent has a Gotal with Obi-Wan's Lightaber attached and Ferus Olin. I spend the resource to cause a Gotal to lose the Force User trait for the phase. Is the lightsaber discarded? Or, since it is already attached, does it keep the lightsaber?

Thanks for the help in clearing this up.

It takes Targeted, Shielding, Edge etc. not Force User, Vehicle, etc.

As Letux says, it removes keywords, not traits. That said, if that does cause the enhancement to become illegal (eg hypothetical enhancement that said "Enhance unit with shielding), then the enhancement would be discarded.
